Null comparison detection stored on a variable not considered on if statement

[soullivaneuh]

Summary of a problem or a feature request

When a null comparison is store on a variable, it not considered by PHPSTan.

It's a retry of #800. There is already #647 and #701 about assignments in conditions, but I'm not sure it's related. For my case, it's not directly an assignment but a comparison stored on a boolean variable.

See the sample. If it's indeed the same issue, sorry for that and feel free to close. 👍

Expected output

Nothing.

Now that I see it, I don’t think it’s the same. Thanks.

This is fixed, but it needs a slightly modified example: https://phpstan.org/r/0de58ea4-35b0-4550-a775-1c604dff53f7

Dependent variables

Thank you for this feature.

I think a software is better if avoids this pattern.
@ondrejmirtes Is there a way to disable Dependent variables feature?
